Roger - Thanks for the detailed analysis and advice. He threw a bullpen today (before I saw Roger’s post). His first few pitches I could tell that he was still leaning back, so I told him to focus on staying upright and balanced, and keeping his head level and pointed toward the plate. The rest of his pitches were down in the zone for “good” strikes, as opposed to tending toward being high and arm side. Definitely progress. We’ll keep working on incorporating the advice in these posts little by little as he becomes comfortable with each new tweak. I’ll post some more video in a few months.

I saw that he increased his stride which is good. However, his arm path is probably slower than before so he needs to work on getting his arm up quicker. Aslo, I noticed that his arm was bent outside 90 degrees of flexion which can be harmful.

Brenk,
If you haven’t already I suggest that you stay on Lets talk pitching and go to Glove to chest vs chest to glove article, read it through and you will find your answer to your son’s problems in there. I could explain it to you but it is already explained in detail there.
Best of luck with solving his problems.
great BaseBall-N
